A new motion is open for debate today in the Economist's online series: "This house believes that the language we speak shapes how we think". Lera Boroditsky is the designated defender of the motion, and I was recruited to be the designated opponent.
In this format, each side submits an opening statement, a rebuttal, and a closing statement. Readers get to comment, and also to vote on the motion. Our opening statements are now live.
As regular LL readers know, my perspective on this question is not all that different from Lera's — see here and here for some past discussion. So when I was invited to participate in the debate, I tried to pass the buck to a more resolute and orthodox anti-Whorfian who has actually done some research on the topic (as I have not). This attempt failed, and in the end, I agreed to play the role. You can be the judge of how well I succeeded.
